A water purifier

Abstract

A water purifier is disclosed. The water purifier comprises a case, a raw water tank, filter elements mounted in the case and a thick water tank mounted in the case. The filter elements comprise RO (reverse osmosis) filter membranes. The thick water tank is used for containing thick water obtained by washing the RO filter membranes. The raw water tank and the thick water tank are communicated. The thick water in the thick water tank can overflow to the raw water tank. The raw water tank and the thick water tank are communicated so that the thick water obtained by washing the RO filter membranes can be cycled and reused, the concentration of the thick water reaches the maximum, waste of the water resource is effectively avoided, additional pipe connection for discharging the thick water is not needed, and the water purifier is flexible and convenient in arrangement positions.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier with an RO reverse osmosis filter core. Background technique [0002] In recent years, as environmental problems have become more and more prominent, people's awareness of healthy diet has gradually increased, such as food hygiene, air quality and water quality safety have become more and more concerned, and the water purification industry has ushered in a period of vigorous development. At present, many water purifiers (water dispensers) on the market are mostly under-kitchen and cabinet-type. The speed of under-kitchen water production is very slow, and it is difficult to realize ready-to-use, which affects the daily use of users. [0003] Most of the vertical cabinet water purifiers are transformed from traditional water dispensers. Because of their large size, they are mostly placed in the living room. Restricted by water source and pipeline, it is not convenient to use R...

AI Technical Summary

Problems solved by technology

Restricted by water source and pipeline, it is not convenient to use RO filter element for filtration, because RO membrane filtration will produce a certain amount of concentrated water, which needs to be discharged. Therefore, many vertical cabinet water purifiers only use microfiltration, Simple filtration such as activated carbon cannot achieve real purified water

Some water purifiers use RO membrane filtration, and an extra concentrated water collection bucket is added, which needs to be drained and emptied regularly, which brings inconvenience to users

Many stand-alone machines have relatively simple functions and are inconvenient to operate and use. Moreover, the concentrated water after washing the RO filter element is directly discharged or dumped, causing a serious waste of water resources.
